Is this video that has already been edited or are you looking for an editing program as well? I only ask because rendering is usually done through the editing software. The more professional programs like Premiere Pro, Sony Vegas and Avid Media Composer give you more control over the rendering process. You can also use programs like CyberLink PowerDirector, Adobe Premiere Elements, Sony Vegas Movie Studio, and Corel VideoStudio just to name a few. If you simply want to re-encode a video to a specific format you can use free programs like MPEG Streamclip (http
/www.squared5.com/) or Handbrake (http
/handbrake.fr/). As far as the rendering process it largely depends on your computer. For example the CPU plays a large part in rendering.
